Hi all, I'm looking to upgrade my pc, I've had my current one for 2 years now. PCPartPicker part list: http://uk.pcpartpicker.com/p/v4kyHx this is my current build, i am looking to upgrade to this PCPartPicker part list: http://uk.pcpartpicker.com/p/pTjPGX basically, what I want to know is, is it worth upgrading to this? Should I get a better gfx card? As I can't be bothered with the bugs I've been getting on most of my games due to having 2 cards, also, how much do you think I should be asking for my current pc? I know they decrease in price a lot second hand. Thank you for your time all!
